Doesn't work?

I have an old EZ site Community Project 2014.11.
It has old recaptcha module (recaptcha v1) that now it doesn't work anymore (since v1 is closed). I have found your code, but when I put it into a form after submit i have always this message in /content/action page:
Captcha: You are a BOT!

I tried to use this extension and I saw that invisibleReCAPTCHATool.js executed before loaded DOM. As a consequence there is no call grecaptcha.execute() after form sumbiting which generate the variable g-recaptcha-response.

Also I had the problem with publishing an object form: The field dbteaminvisiblerecaptcha was not validated
